Dear Mariette,
The Xray does appear to show an area of dilation, or aneurysm, involving the inferior vena cava (IVC). There are many possible explanations for this, although I believe that knowing the specific cause won't change the management. If you've suffered
recurrentRecurrent cystitis PE's despite adequate anticoagulation with Warfarin (Coumadin), it is time to consider placing a filter in the IVC to prevent future PE's. This needs to be discussed with a specialist.
As you know, this forum is not intended to diagnose or manage the particulars of a specific patient's course. Instead, we try to give general recommendations that offer some educational value to readers who may consult this page. Regrettably, I believe that our ability to advise you on this issue has been exceeded. As such , it would be wise to consult with experienced physicians, especially at a large hospital or academic medical center in your area.
Best of luck.
